Hello,
I'm trying to plan a test system which will include the PXIe-5413 Waveform Generator module. I'm planning to deploy the 2 channel version, but I have 24 channels I would like to test with this device.
Also in my design are a number of mux/matrix switch modules. I was expecting to utilize 24 channels of one of these devices, specifically PXIe-2737 2-wire 4x64 Matrix switch, to switch the specific channel under test to the PXIe-5413.
The problem I have is that the PXIe-5413 produces the waveform on a SMA connector. I expected to find a cable that goes from SMA to unterminated wire on the other end, but I have not been able to locate anything. Alternatively, there might be some sort of breakout box with screw terminals for this, but I am unable to find this as well.
Does anyone have any suggestions on how to solve this problem?
Is there some flaw in my thinking to "breakout" the SMA connection?
I realize the SMA cable is a 1 wire cable, and the waveform generator is single ended, so this may seem incongruent with the 2-wire switch, but I have the resources available on the 2-wire switch, so I plan to simply leave the second wire un-utilized, or connected to ground for the benefit of the UUT. Is there a flaw in this logic?
Any help you can provide will be greatly appreciated. I'm looking for a "clean" solution, but I'm always open to creative ideas.
Thank you,
Alex

Hi Alex,
I was checking about any available SMA converter in NI and the one we have is the SMA-BNC connector: http://www.ni.com/en-us/support/model.smb-bnc-coaxial-cable.html
You can then use a 2-wire to BNC converter, that way you will have the 2 wires for the switch.
